| 186 | bool "Enable an early debug UART for debugging" |
| 187 | help |
| 188 | The debug UART is intended for use very early in U-Boot to debug |
| 189 | problems when an ICE or other debug mechanism is not available. |
| 190 | |
| 191 | To use it you should: |
| 192 | - Make sure your UART supports this interface |
| 193 | - Enable CONFIG_DEBUG_UART |
| 194 | - Enable the CONFIG for your UART to tell it to provide this interface |
| 195 | (e.g. CONFIG_DEBUG_UART_NS16550) |
| 196 | - Define the required settings as needed (see below) |
| 197 | - Call debug_uart_init() before use |
| 198 | - Call debug_uart_putc() to output a character |
| 199 | |
| 200 | Depending on your platform it may be possible to use this UART before |
| 201 | a stack is available. |
| 202 | |
| 203 | If your UART does not support this interface you can probably add |
| 204 | support quite easily. Remember that you cannot use driver model and |
| 205 | it is preferred to use no stack. |
| 206 | |
| 207 | You must not use this UART once driver model is working and the |
| 208 | serial drivers are up and running (done in serial_init()). Otherwise |
| 209 | the drivers may conflict and you will get strange output. |

| 682 | Enable this option to allow device-tree control of the driver. |

| 684 | Normally this driver is controlled by the following options: |
| 685 | |
| 686 | CONFIG_SYS_NS16550_PORT_MAPPED - indicates that port I/O is used for |
| 687 | access. If not enabled, then the UART is memory-mapped. |
| 688 | CONFIG_SYS_NS16550_MEM32 - if memory-mapped, indicates that 32-bit |
| 689 | access should be used (instead of 8-bit) |
| 690 | CONFIG_SYS_NS16550_REG_SIZE - indicates register width and also |
| 691 | endianness. If positive, big-endian access is used. If negative, |
| 692 | little-endian is used. |
| 693 | |
| 694 | It is not a good practice for a driver to be statically configured, |
